2 Investigation

The resistance to root penetration has been determined according to CEN/TS 14416:2014 – Geosynthetic barriers – Test method for determining the resistance to roots. Three test specimens and one reference specimen have been built up by Mr P. Golverdingen of Kiwa BDA Testing B.V. on 29 may 2018. See annex II for photos of the buildup of the test specimens. The test duration has been determined at six weeks. After this period the seeds appeared to have been developed to healthy young plants. The investigation has been performed in period from week 22 up to and including week 28, 2018.

3 Results

After the growing period of six weeks no penetration into or through the test specimens is observed. The reference with the 20 mm thick layer of bitumen 85/40 showed root penetration. See also photos in annex III. Remarks: The results are only related to the investigated samples, products and/or systems. Kiwa BDA Testing B.V. is not liable for interpretations or conclusions that are made in consequence of the results obtained. The uncertainty of measurement can be retrieved at Kiwa BDA Testing B.V.
